Is there any such thing as a ‘self-realised’ person?
Firstly I will consider the common use of the term ‘self-realisation’ as a translation of the Sanskrit terms ātma-jñāna or ātmānubhava, which respectively mean self-knowledge and self-experience in the sense of experiencing or being clearly aware of ourself as we really are. Though ‘realise’ can mean to recognise, understand, ascertain or become clearly aware of something, it is a rather vague and ambiguous term to use in this context, because it has various other meanings such as to accomplish, achieve, fulfil, actualise, effect, bring about, acquire or cause to happen, so ‘self-realisation’ is not the most appropriate term to use as a translation of ātma-jñāna or ātmānubhava, particularly since in psychology the term ‘self-realisation’ means self-actualisation or self-fulfilment in the sense of achieving one’s full personal potential.
Though he did not speak much English, Sri Ramana understood it enough to recognise that ‘self-realisation’ is not a particularly appropriate term to use in the context of his teachings. He therefore used to joke about it saying that ourself is always real, so there is no need for it to be realised, and that the problem is that we have realised what is unreal (that is, we have made the unreal seem to be real), so what we now need to do is not to realise our ever-real self but only to unrealise everything that is unreal, particularly our seemingly real ego, which is the root cause of the seeming reality of everything else.
